Title: Process and apparatus for the generation of steam
IPC: F22B27/06
Filed: 1928-04-02
Abstract: 313,681. Bartsch, A. April 2, 1928. Heating by direct contact of steam; water-tube boilers.-Water preheated under pressure in a tube system is atomized and mixed with superheated steam in a rotary evaporator thus generating further steam which is led off for use through a superheater. Water supplied by a pump 5 to preheating tubes 17 arranged around and above the furnace chamber 16 flows from a collector 14 through regulators 36, 37, 39 into a rotary evaporator 2 having ribs or vanes which draw steam from a superheater header 12 and mix it with the heated and sprayed water. Steam is led from the rotary evaporator into the distributing header 11 of the superheater 8, from which it passes through a further superheater 44 to the engine 1. Surplus steam passes off though a loaded valve 49 to a regenerative accumulator 48. The feed regulator 39 contains a piston 54 acted upon in one direction by the steam pressure and in the other direction by the feed supply pressure and the pressure of a spring 53. The movement of the piston controls the passage of water through openings in a surrounding sleeve. The sleeve may be moved by hand angularly to adjust the size of the water passage. The piston also operates through levers 55 the valves 58, 62, 63 controlling the supplies of fuel, air and steam respectively to a rotary mixer and atomizer 3 supplying fuel to the main burner 20. A pressure operated valve 36 cuts off the water supply when the pump pressure falls below the steam pressure, and upon a breakdown of the pump, a spring 65 operates the water return valve 37, the fuel return valve 66, and the air return valve 67. At starting, water is circulated by the pump 5 or by a hand pump 71 through the preheating tubes and back to the pump through the valve 37, and fuel is supplied to an auxiliary burner 29 by a hand pump 70 and air by an,auxiliary fan 6. A solid fuel furnace 32 may be used for starting in place of the burner 29. High pressure steam may be generated indirectly by the circulation of steam from the rotary evaporator through coils 73 in water drum 72. Uncondensed steam from the coils flows through a feed heater 74 of the high pressure generator and is led into a collector 75, from which it is drawn by the feed pump 5.

Title: Compact disc play-back device
Inventor: BAAS DIETER
IPC: G11B27/30
Filed: 1988-06-01
Abstract: Compact disk readers first read the index of the content of a compact disk introduced to be read and record it in total or in part. In spite of the high degree of redundancy of such indexes, it may happen that they are unreadable for compact disk readers. To allow a compact disk reader to work in spite of the unreadability of the index, the scanning device of the compact disk reader looks for the end of the index. The part of the compact disk which follows the index can then be reproduced. The index data are recovered during reproduction of the compact disk or during a previous stage by stage scanning.

Title: Musical sound signal generator
Inventor: KAWASHIMA SUSUMU
IPC: G10H7/00
Filed: 1988-01-06
Abstract: PURPOSE:To play sampled sounds without hindrance by generating a musical sound signal from an incorporated sound source means and sampling this signal to store it in a storage means at the time of not inputting an external sound signal for a certain time. CONSTITUTION:When it is indicated by a sampling indication means 4 that the sound signal is taken in from a sound signal input means 1 and its waveform sample data is written in a storage means 3, a sampling control means 5 starts counting of a prescribed time and checks whether a rise detecting means 5 detects the rise of the sound signal during this time or not. When the rise of the sound signal from the sound signal input means 1 is detected then, waveform sample data of this sound signal is stored in the storage means 3 as normal. Meanwhile, when the rise of the sound signal is not detected during said prescribed time, the musical sound signal is generated from an incorporated sound source means 2 and its waveform sample data is written in the storage means 3. The mode is automatically switched to the internal sound sampling mode to store the musical sound signal in the storage means 3 in this manner. Thus, sampled sounds are played without hindrance.

Title: Image reader
Inventor: OTANI MIYUKI
IPC: G06T1/00
Filed: 1988-01-08
Abstract: PURPOSE:To obtain same one image from one same original by setting a slice level value for an original image read first binarizing it then storing it and detecting whether an original read next is another one or not. CONSTITUTION:After the control is started, whether a slice level value is preliminarily designated by an external equipment or not is decided, and if the level value is designated, it is set, and a CPU 208 outputs the value as it is to a binarization circuit 205. In case the slice level value is not designated, whether the designation by the external equipment is the original-identical mode or not is decided, if so, slice level values preliminarily stored in a memory device 212 are read out serially and outputted to the circuit 205. In case said mode is not designated, a texture detection circuit 204 detects the maximum density values and minimum density values in the unit of line in the scanning direction are detected. The CPU 208 fetches thus obtained values, calculates their average, and outputs the result to the circuit 205 as a slice level value, and thus the slice level value in the memory device 212 is rewritten.

Title: Associative memory
Inventor: TANJI MASAYUKI
IPC: G06F17/30
Filed: 1985-01-11
Abstract: PURPOSE:To reduce reference to a directory remarkably and speed up associative action for continuous plural data by storing plural data to be retrieved in a retrieval data memory in an associative memory, comparing higher part of a retrieval data and corresponding higher part of data in the data memory, and comparing the whole parts when the two coincide. CONSTITUTION:In the case where the number of data in the directory is N, and the number of retrieval data is K, it was hitherto necessary to refer to a directory NK/2 times on an average until all retrieval is completed. However, when the value of the power of 2 found by a comparator at negligible number of bits and the number of retrieval data coincide, whole retrieval is completed by retrieving the directory 2N times and retrieving the retrieval data memory K(K+1)/2 times at a maximum. Generally, N is greater than K. For instance, when N is 1000 and K is 8, average number of times of the directory before this invention was 4000 times. On the contrary, after execution of this invention, 2000 times of reference of the directory and 36 times reference of the retrieval data memory at a maximum become sufficient.
